2.6 Installing the AP

2.6.1 Installing the Device on a Wall

A wall for installing the device needs to meet the following requirements:



The wall can bear the weight of four times the total weight of the device and mounting bracket without damage.



When the tightening torx of a screw reaches 5 N•m, the screw still properly works, without crack or

damage on the wall.

Mounting kits and expansion bolts are required to install the AP on a wall. The procedures are as follows:

When fixing the sheet metal mounting bracket, ensure that the arrows point upwards on the

label.

1. Fix a mounting bracket to the wall against the wall and mark the drilling positions

through holes of the bracket.

Cable or Device

Description

USB flash drive or USB cable

Connects to a USB flash drive or other storage devices to extend the storage space of the AP. The USB2.0 standard is supported.

Network cable



The service network cable and PoE input cable cannot be connected to the console port. Otherwise, the AP may be damaged when using PoE power supply.



If the AP needs to connect to the Ethernet, ensure that the Ethernet cable is working properly. If the Ethernet cable is not working properly, for example, RJ45 connectors are short-circuited, the AP may fail to be powered on or fail to work. Before connecting an Ethernet cable to the AP, use the cable test tool to check whether the cable is qualified. If the cable is unqualified, replace it.



For the supported network cable types and length requirements, see Connecting Network Cables.

DC power adapter

When the AP uses the DC power supply, use a power adapter for power supply; otherwise, the AP may be damaged.

RF cable

Connects an antenna to an IoT card through a radio cable.

Antenna

Connects a 2.4 GHz or 5 GHz antenna to the AP to send and receive wireless signals.The port type is N-type female.The port is applicable only to an AP that supports external antennas.

Antenna

Connects a 5 GHz antenna to the AP to send and receive wireless signals.The port type is N-type female.The port is applicable only to an AP that supports external antennas.



No priorities are distinguished for DC and PoE power supply modes, DC and GE/PoE_IN support HSB.



Two PoE channels have no priority and can serve as HSB for each other when they have the same input power type.

When installing a cable, you must make a drip loop to prevent water from flowing into devices along the cable. For the method of making the drip loop, see 5.8 Guide to Making Drip Loops.

Pay attention to the following points when bundling the cables:



Different types of cables must be separately routed with the minimum spacing of 30 mm and cannot be entangled or crossed. Cables should be parallel or separated using dedicated separators.



Bundled cables are closely arranged, straight, tidy, and undamaged.



Connecting UTP network cables to 5GE interfaces poses high risks and is not recommended. The causes are as follows:



802.3bz requires that the ALSNR value for alien crosstalk between network cables be greater than 0, but the standards for Cat5e and Cat6 unshielded twisted pairs do not specify the required ALSNR value. Therefore, such cables may not meet the crosstalk requirement in 802.3bz, causing severe problems such as continuous packet loss.



According the cabling specification TIA TSB-5021, using Cat5e and Cat6 cables for 5G poses high risks.



Currently, no clear onsite testing or evaluation method is available for checking whether ALSNR of cables conforms to 802.3bz.



If Cat5e and Cat6 unshielded twisted pairs do not meet the 5G requirement, you are advised to replace them with shielded twisted pairs or reduce the rate of interfaces to 2.5G.

Connecting Antennas

Connect the antennas delivered in the installation accessory package of the AP to the 2.4G/5G

RF ports on the AP, tighten the nuts (with a torque of 0.8 N•m), and adjust antenna angles as

required.

Do not connect the antennas delivered in the installation accessory package of the AP to 5G antenna interfaces. Otherwise, the AP and antennas may be damaged. The 5G antenna interfaces can be connected only to remote antennas through feeder cables.

2.8 Connecting the Security Lock

There is a security slot on the device. You can lock the device to an immovable object to prevent theft. The detailed procedures are as follows:

1. Fasten the cable of the security lock to an immovable object around.

2. Insert the security lock into the security slot and lock it.
